Axle housing and method of maxing the same



Mam 4 mi@ L V. V. TORBENSEN AXLE Housme AND METHOD oF MAKING THE SAME Filled Dec. '8, 1922 WENN 2 QNM.

g f gings To @il whom Bo it movin @not i'. Vina-o ik @minimising s. citizen oi 'vibo Usui/nd Signos. and s. resident of Cleveland, 'omini of Cnyshogs., Sini-s of subjeced and which may bemande/stuffed' at s ressonabio A furhsr objeo' of dus invenision is to provide method of mnnuiaotuiing an mile liousing from roiled siasi by equ-ipmsni which may 'ne provided nl, a reasonable cost.

A further objsci, of the invenvsion is to proi vide an axle Construction in which ail of ille parts are so designed as to be subjected only to the classes of sresses dint 'disy are adapt ed to withstand.

Other objects of zhs invsntion and inne features of novelty Wili ne apparent from the following description taken in connection with the accompanying drawings, of which:

Figure i is a. sido elevngion o s .ieng'ii oi tube from which an axle is for; ied, according to my method;

Fig. 2 is an and elevaiion of the saine Fig. 3 is a View of the tube shown in Fig. i after he first and soeond operations in which the ends of iii@ tubs are swnged 'i-,o size and a semi-oirouiar section is infini the middle portion o the tube;

Fig. i is a transverse s tion on the lino 1 4 of Fig. 3;

Fig. 5 is a View similar to 3 lou snowing the axle ar the third opai'aioii, in which the middle portion is sim; 1 one half of the enlarged middle housing;

Fig. 6 is @transverse section on *Jie line 6-6 of Fig. 5;

Fig. 7 is a. side elevaion of s. formbfi pien-a to be inserted at the middle of the housing to complete the enlarged middl@l part of the housing;

Fig. 8 is a transverse section on the line 8-8 of Fig. i

iii/Risi Elfe. 263,553?.

Wig. is sido sievstion oZ ihn oompioid housing; and

Fig. ld is n transverse section on the line iii-i0 of Fig. 9.

Referring to 'das drawings, 10 indio-aos@ lsngfi sirnigii, cyiindricui and. preferably sesniiess mbo, o the proper stesi for Wiiisuanding; iii@ sress o which an and@ housing is subjeced. vWhiiia i have illustrated a housing made of oyiindricai tubing ilo bs understood square iuong or of sii-er orosssiionmay be use/d in lining :my invontion. iii@ iifs oper- .i ion, may' ne performed on a `punch press or n milling maniiino or in any other suitabie manner, ai asini-'circular session is cul: from ish@ middio portion of ns tube, as indicated mi; li, thereby providing the llongitudinai edgss 12 sind. he samifoirculnr @mnsverse edges i3. if time out siway portion is mirrored in n punch prs it will' probably los sdvisafbis to inr n suitably formed mnndrei wiiiin ille tube to support the metal during the sliearin operation. s

By the second ogeruiion, the ends of izubo ars swnged in an ordinary swnging mai chine reduce zhsir diameter to that desired to form the Wheel. journals. By the third operation ihn middio pori-ion of the housing is beni., in suitable. diss, to ubsm iiaiiy lle forni shown in Figs. 5' and 6, to provide one nali of fails enlarged @mitral pon tion olf: ibs 'housingn which sho nsusi di feranial is loomed.

The @relied piece 1li, shown in Figs. 7 and 8, is ornied on siamping press from fiat ensei si" :i is tedino ith-e opening ai; Shins nm: is porilon o'r fails nousing, a indiin Fig. 9 'ho abuing 4edges are Welded or limzed, as 'may lio preferred, to soeur@ piece in posiion. As shown in Figs. 9 and i0, the axle housing thus formed has openings i5 on ino iront and rear sides and these sides are subsanially fist so as i0 De adapted to reive sui'abie coser plass or oils@- paris of 'ne axis. The matsr nf iin- 'l 'she housing from the sings illusraied Figs. 9 und i0 'forms no pam of the pw"- .snis invenzion, and a description of the addi- 'ionai operaiions is, lierefore, omitted.. as housing illusiraed in these figures is n {P3-'Qi i i@ al; the .middle of the housing, v ai with the tubular end porjtions article ready for the machining o two halves ere welded together by loingitndinel seems., end et the seme time is e eoinnieroieliy feesible proposion on :recount of the low cost of manufacture.

Having thus described any invention, what l oleirn is:

i. The ,herein described method or" moli ing an axle housing which consiste in telting e tnbe of the required, length :intl ont ting sggey substantially oneioelf of e iniddle section thereof, the remeportion of seid section nwe-'2f 'roni tile oi the tube to form e part o tlie eniergeof center o' the housing and then Securing to the thus partially formed housing 'formed section complementary" to seid bent portion.

2. The herein described method oi? ineining en eerie housing wif-.ion consists in teli-- ing a tube of the required lengt?B end ontting wey snbstentieiiy onena' of iniddle section thereof bending the reineinine.' portion oi seid section away from the eine of the tube, lont in the plane there-or' to forni e part of the enlarged center oiz the "housing and then welding in abetting relation to the edges seid remain portion f? etnici section a formed section eonipiementery to said bent portion.

3. The herein deeeriir ing en eine housing ing e. tube of tire required lengtli ond entf ting ewey o substantiel portion of e middle section thereof end tir-ere'l` leevingj en ope-ning in seid middle Section ving longitndi nel ed en extending in the L ction of the anis el. the tube end ende snbetentieiiy right angles thereto, bending the remaining portion of seid section from the exis of 'the tube to 'form e pei-t 0;? tile enlarged center or" the honoring and then welding in abutting reletion to seine seid edges er ormed section complementan? to Seid bent portion The iierein described method of malren orgie housing which consiste in teke ciicnier tube of the required length nuttin# away from the middle thereof e section or Substantially semi-circuler cross section, bending the remaining se1ni-circuler portion away from the exis of the tube to forni port of the enlarged center of the housing and welding in place of seid cntewey section n formed section complementary to the seid bent portion.

is e new article of mennfactxfre, an .axle housing having an enlarged center and tubular ends, said ends and one side of seid leigred center beine' intefrral and the opposite eide of seid ennrged center being :in arched piece that is welded in position.

55, Ae e new article of manufacture, en onlie housing having an enlarged center and tubular ends, seid ends and the lower side of Seid enlarged center being integral and the upper side of seid enlarged center being en arched piece that is welded in position.

Y. As e new article of manufacture, en housing leaving en enlarged centel` and tubular end portions the inner ends of which are in planes normal to the exis of the tube end neve welded in abutting relation theren piece of metal forming Substantially the zipper lie-lf of the enlarged center of the iionsino, the lower half of seid enlarged center oeing integral with seid tubular end portions. A

8. .like new article of manufacture, en axle housing formed from a length of seamless tubing7 the middle portion of seid lengtlroif tnoin constituting the lowei` half of the enler center of the housing and the-opper lieif tliereoi consisting of en inserted piece "which is weldedv in lace.

9. en e new article of manu 'eet-nre, enA

exle lionsine formed from a length of seam less tubing ieving substantially one-half of e middle section thereof cut awe remainder of seid middle section lieing bent. away from the exis of the tube and havin opposed thereto n complementary piece, Sei piece and said nent portion forming the enlerged center of the housing and the spacinge? therebetween providing front end roer openings in seid enlerged center'.
